The disclosed embodiments relate generally to signal processing and inparticular to systems and methods for providing enhanced audio material.

BACKGROUND

Unless otherwise indicated herein, the approaches described in thissection are not prior art to the claims in this application and are notadmitted to be prior art by inclusion in this section.

Psychoacoustics is the scientific study of sound perception. Morespecifically, it is the branch of science studying the psychological andphysiological responses associated with sound (including speech andmusic).

Hearing is not a purely mechanical phenomenon of wave propagation, butis also a sensory and perceptual event. In other words, when a personhears something, that something arrives at the ear as a mechanical soundwave traveling through the air; but within the ear it is transformedinto neural action potentials. These nerve pulses then travel to thebrain where they are perceived. Hence, in many problems in acoustics,such as for audio processing, it may be advantageous to take intoaccount not just the mechanics of the environment, but also the factthat both the ear and the brain are involved in a person's listeningexperience.

There remains a need for improved systems and methods for processingaudio signals to achieve desired psychoacoustic properties.

SUMMARY

Described herein are systems and methods for psychoacoustic processingof audio materials. In some embodiments, a psychoacoustic process foracoustically enhancing audio material provides a more engaging listenerexperience by creating specific physical stimuli. In some embodiments, aprocess for providing enhanced audio material includes a combination ofre-harmonization and auditory processing techniques, wherein a pluralityof filtered audio cues are sampled, created and down-mixed into a finalmusic file output, which is designed to trigger specific effects on thefunction of the body and the brain.

In some embodiments, a process for providing enhanced audio material(sometimes referred to herein as “Rezonyx”) integrates new methods andprocesses with proven existing psychoacoustic principles to create thedesired material. In some embodiments, harmonic data is altered toprovide a desired result, but the timbre, dynamics and integral soundqualities of the original material is preserved. Such processes may beapplied to prerecorded or live audio material via software or hardware,for example.

In some embodiments, a Rezonyx process has been configured in order toimprove the experience of audio engagement, and may be designed for anyaudience where the importance of the audio material is paramount to thevalue of the content.

In some embodiments, by introducing a harmonically layered combinationof frequencies and binaural beats to existing audio material, the braincan be induced into states of focused concentration, deep relaxation,intense creativity, and more, while stimulating various parts of yourbrain to work together in synchronization. By stimulating the brain toproduce or decrease certain brainwave bands, a variety of mental statesand emotional reactions, including meditation, excitation, motivation,anxiety, irritation, sexual excitement, relaxation, and spiritualism,can be achieved.

In some embodiments, the result of embedding Alpha waves into musiclistening provides a very relaxing experience for the listener.

In some embodiments, polyphonic retuning may be used to retune a varietyof instruments, e.g., away from the standard of 12-tone temperamentscaling and A 440 base reference to an optimal frequency for each notein the scale. By recalibrating the frequencies of sound using systemsand methods described herein, notes within the music and other audiomaterial may resonate better with the human physiology. Such newprocesses of tuning instruments may provide musicians and artists with anew way to create music that provides a more engaging experience.

These as well as other aspects and advantages will become apparent tothose of ordinary skill in the art by reading the following detaileddescription, with reference where appropriate to the accompanyingdrawings.

DESCRIPTION OF EMBODIMENTS I. Overview

Described herein are systems and methods for psychoacoustic processingof audio materials. In the following description, for purposes ofexplanation, numerous examples and specific details are set forth inorder to provide a thorough understanding of the aspects of the systemsand methods. It will be evident, however, to one skilled in the art thatthe present invention as defined by the claims may include some or allof the features in these examples alone or in combination with otherfeatures described below, and may further include modifications andequivalents of the features and concepts described herein.

II. Example Embodiment: Rezonyx System

Referring to FIG. 1, in some embodiments, a Rezonyx system 100 forprocessing an input sound 102 to an enhanced output sound 180, mayinclude an input transducer 110 (which may also be referred to as an“input converter”, “analog to digital converter”, or “A/D converter”)for converting the input sound 102 to an electric input signal, and anoutput transducer 170 (which may also be referred to as an “outputconverter”, “digital to analog converter”, or “D/A converter”) forconverting a processed electric output signal to an output sound 180. Insome embodiments, a forward path may be defined between the A/Dconverter 110 and the D/A converter 170, and may include a reharmonizer120 and signal processing unit 122, a splitter 130 and an amplifiermodule 140 followed by a processor module 150. In some embodiments,amplifier module 140 and processor 150 may be collectively referred toas a Rezonyx processor.

In some embodiments, reharmonizer 120 may retune or reharmonize theinput signal to a new base frequency (e.g., adjusted from the standardbase frequency where note A has a frequency of 440 Hz, also sometimesreferred to as A440). In some embodiments, splitter 130 may split orsample the harmonized (or in some embodiments, unharmonized) audiomaterial into a number of desired stages, or frequency bands. Amplifiermodule 140 may include one or more parallel signal amplifiers 140-1,140-2, 140-3, 140-4, 140-5, each configure to amplify a stage of theaudio material sampled by the splitter 130. The processor module 150,and/or each processing unit 150-1, 150-2, 150-3, 150-4, 150-5, may thenfilter and/or delay the amplified input signal of one or more of thestages to a preset spectral frequency band, e.g., selected by inputdata. In some embodiments, a separate processor may be used for eachfrequency processed as shown in FIG. 1, but the system 100 could utilizethe power of a single DSP, e.g., if the architecture is optimized so nolatency occurs in the processed signal.

After Rezonyx processing and retuning of one or more of the signal bandsor stages, a signal mux interface 160 may downmix or multiplex all ofthe parallel signals, e.g., with an LG-estimator unit for estimatingloop gain in each frequency band. In some embodiments, the muxer 160 mayprovide the enhanced material to the digital to analog convertor 170,which is then delivered back as an enhanced audio stream 180. In someembodiments, the mux 160 and/or other modules may be used to overlay oneor more processed frequency bands onto the audio material to createenhanced audio material.

In some embodiments, the enhanced audio stream 180 may be formatted asit was at input and therefore does not require a proprietary player toplay the information back. All filters may be engaged or disengaged asdesired through the process 100. Levels of filtered information can bedirectly controlled, for example, at the muxer 160.

In some embodiments, a Rezonyx retuning system such as system 100 may beused to process audio material by reharmonizing the base frequency ofthe material from the standard 400 Hz, for example, to achieve desiredfrequencies for one or more notes to optimize the psychoacousticproperties of the material. Table 1 below, for example, shows a numberof music notes retuned to their optimal psychoacoustic frequencies. Thefar right column described the tuning shift in cents from standard a 440Hz tuning (i.e., where the “A” note is tuned to 440 Hz) to achieve thedesired frequency for each note. See also section III below for anoverview of properties and potential benefits of such desiredfrequencies in accordance with psychoacoustic principles. One skilled inthe art will appreciate that Table 1 represents shifts to examplefrequencies within one octave. Notes within other octaves may undergosimilar shifts using the principles shown and described herein.

TABLE 1 Music Notes with Harmonic Frequencies and Tuning ShiftCorresponding Shift from Desired Frequency of Standard A440 HzFrequency/Note Retuned “A” Note (in cents) 174 Hz = F3 438.48 Hz −06cents 285 Hz = C#4 452.37 Hz +48 cents 396 Hz = G4 444.34 Hz +17 cents417 Hz = G#4 441.78 Hz  +7 cents 528 Hz = C5   444 Hz +16 cents 639 Hz =D#5 451.84 Hz +46 cents 741 Hz = F#5 440.60 Hz  +2 cents 852 Hz = G#5451.33 Hz +44 cents 963 Hz = B5 428.96 Hz −44 cents

Turning now to FIG. 2, a flowchart illustrating a method 200 of using anexemplary Rezonyx system to for psychoacoustic processing of audiomaterial may comprise a multi-stage process. For example, a first stagemay involve digitizing 210 an audio input (e.g., using an analog todigital converter as described above with respect to FIG. 1) andreharmonizing 220 the audio material to a desired base frequency. Forexample, reharmonizing the base note by +16 cents may shift the basenote from 440 Hz to 444 Hz, thereby shifting the corresponding C5 noteto a desired frequency of 528 Hz.

Such reharmonization may be used to bring the audio source material intoa tuning frequency that is proven to alter mind and body process. In allprerecorded music material there is almost always specific frequenciesin which musical overtones occur resonances that relate to notes on themusical scale. Using today's A440 base tuning reference (i.e., A=440Hz), the frequencies generated by notes on the musical scale may be outof alignment with our body. In contrast, reharmonizing or shifting thebase note (and/or one or more other notes of the scale) may provide morenatural tuning frequencies and an overall more enjoyable, moving, andeffective listening experience.

In some embodiments, harmonization of the input signal 220 may beprovided by software that instructs a digital signal processor toperform this transform. In some embodiments, such a process can beutilized within software of embedded in silicon for a variety ofdevices.

In some embodiments, a second stage process may be achieved by samplingin 230, duplicating the reharmonized audio material 240, and filteringthe stages 250 to create a plurality of narrow frequency bands centeredaround the harmonic frequencies scientifically associated with abilityto alter the body or brain process. The core frequencies chosen dependson the outcome the listener or organization requires. A list offrequencies and properties is detailed below, under the section titled“III: Frequency Band Principles”. The frequencies may be selected withinsoftware, or may be set to preset buttons, or accessed via a menu orother interface on a hardware device.

These narrow frequency bands may be created using harmonic filters whichsample the harmonized audio material in stages, duplicate the reharmonized material then filter out all frequencies not within thechosen band structure, for example using a high Q setting. A high Qsetting provides a soundstage where the introduced frequencies arelargely imperceptible to the human ear as hearing is comparativelyinsensitive to extremely narrow, high Q resonances, unlike broad, low Qresonances, which are very recognizable.

Once the stages of harmonized audio material are filtered to create thedesired band structure, the material may be downmixed 260 or multiplexedto provide a reharmonized and enhanced audio output. In someembodiments, the downmixed material may be converted back to analogbefore outputting the enhanced audio output (e.g., as shown in FIG. 1.)

With audio material processed by Rezonyx the program material providescapabilities that can be altered during the stream or fixed for adesired result and the beginning of the stream. Rezonyx encoded audioand/or data provides the ability to create engagement, excitement,relaxation, and a number of other human based states. The Rezonyxprocess may happen at multiple points. For example, one such point is atpoint of engagement in the device, e.g., live processing the incomingaudio material. In this method the process may be embedded into siliconor a media player, decoder or device with software. Another such pointis where the program material (e.g., audio and/or video) may be encodedor finalized into the media file.

Turning now to FIG. 3, a schematic block diagram of an example systemand method 300 for encoding and preprocessing of an audio and/or videoprogram file 310 is shown. In this example, the file 310 is input intoan interface 320, e.g., through a port or API interface. A hardwareencoding device 330 may encode the file for manipulation by the hardware(e.g., digitization and/or format encoding as desired). A Rezonyxencoding module 340, e.g., implemented as a software module, hardwaremodule, or a combination thereof, may be used to reharmonize, sample,filter and/or process the file to create the desired frequency/notecharacteristics, e.g., using a method 200 of FIG. 2 and/or principles ofsystem 100 of FIG. 1. In some embodiments, encoding module 340 compriseshardware and/or software instructions for shifting, retuning and/orfiltering one or more stages or frequency bands in the audio material.In some embodiments, each retuned frequency corresponds to a musicalnote, as shown in Table 1, for example, such that retuning one or morenotes (referred to herein as “polyphonic retuning”) adjusts and filtersthe frequency of multiple notes in the original audio material. Aftersuch processing and downmixing or multiplexing of the various stages orbands, the resulting Rezonyx processed program file 350 may then bestored and/or distributed 360 to users, e.g., via a network.

Referring to FIG. 4, a schematic block diagram is used to illustrate anexample system 400 and method for live processing of audio and/or videoprogram material in accordance with an example embodiment. In thisexample, a stored or pre-recorded audio and/or video program file 410,or data, may be sent or distributed, e.g., over a network ordistribution cloud 420, to a Rezonyx processing device 430. In someembodiments, the device may include one or more decoders 440 and/orRezonyx processing modules 450-1, 450-2 and/or 450-3, e.g., to retuneone or more frequencies of the material in accordance with thepsychoacoustic principles and methods described herein. In someembodiments, the device 430 may include a player 460 to provide outputof one or more portions of the processed data, e.g., to provide anoutput of particular notes, stages or samples during processing, and/orto play Rezonyx-processed material in “real-time” (e.g., as it isprocessed). In some embodiments, Rezonyx-processed program files 470 areoutput from the system 400, and may be stored, transmitted, and/orplayed by a user as desired.

II. Example: Polyphonic Rezonyx Tuning

In some embodiments, a method of retuning an instrument involvesshifting or retuning a combination of frequencies, where each frequencycorresponds to a musical note. For example, rather than retuning thebase frequency to achieve a desired frequency shift of a particular notein a selection of audio material, each frequency relating a musical notein the audio signal may be transformed by shifting its frequency, e.g.,by the amount shown in Table 1 above. Is such embodiments, each note,and therefore each frequency relating to that note, may be shifted ortransformed so it resonates with the physiology of the human body (e.g.,in accordance with the principles or characteristics described below insection III).

As a musical scale over 1 octave comprises of 12 notes (C, C#, D, D#, E,F, F#, G, G#, A, A#, B) each of these notes has a correspondingfrequency over 1 octave, and therefore over 3 octaves there are 36 notesand frequencies.

The ability to harmonically retune or shift one or a plurality of thesenotes so they are in tune with human physiology provides a polyphonicretuning system where music is tuned to the human body, as opposed to amathematical algorithm where each note is divisible by math—e.g., inaccordance with standard harmonic divisions as shown in FIG. 5.

As discussed above, Table 1 above provides a list of musical notes andcorresponding frequencies and the representative amount of transforming,or retuning, to take place to achieve the example desired frequency foreach note (as listed in the left hand column). The shift in cents (righthand column of Table 1) describes the amount of harmonic retuning totake place for each note within the example octave. In some embodiments,a plurality of these notes are utilized and retuned together, therebyproviding for polyphonic shifting of notes, e.g., from Pythagorean orequal temperament scaling to a physiological harmonic tuning as a basefor the Rezonyx system, e.g. using the system 100 of FIG. 1 and/ormethod 200 of FIG. 2. In some embodiments, such multi-note retuning maybe performed live (e.g., as shown and described above with reference toFIG. 3) or post-processed on stored audio material (e.g., as shown anddescribed above with reference to FIG. 4).

Referring to FIG. 6, in some embodiments, an example Rezonyx method 600may be a system whereby musical instruments can be tuned to the specificRezonyx selected frequencies (e.g., frequencies from Table 1 above)relating to musical notes in the musical scale. For example, such amethod 600 may include digitizing an audio input 610, e.g., using an A/Dconverter 110 as shown in FIG. 1. The digitized signal may then besampled 620 into stages for processing, e.g., using a splitter 130 ofFIG. 1. In some embodiments, the signal may be reharmonized or retunedto a new base frequency before splitting as described above. In someembodiments, such reharmonizing step may not be used.

Following splitting of the signal into desired frequency bands, e.g.,each band corresponding to a musical note in the spectrum of notes usedin the audio material, each band may be tuned and/or filtered, e.g., asdescribed above with respect to FIGS. 1 and 2, to provide an optimalretuned frequency for each note. Such “polyphonic retuning” 630 of thestages of material may be performed in parallel, for example, usingRezonyx amplifiers 140 and processors 150 as shown and described herein.Once all notes are retuned, the audio material may be multiplexed, ordownmixed, e.g., using a mux 160 of system 100.

In some embodiments, such a polyphonic retuning method may be applied tokeyboards and other fretless instruments. In some embodiments frettedinstruments such as guitars, bass, etc. may require or be fitted with anew fretting system for each string. In some embodiments, fretlessinstruments would be able to tune to these frequencies and fingers couldplay the notes without frets.

In some embodiments, a purpose of a Rezonyx tuning system using thefrequencies shown in Table 1, or other desired frequencies and/orfrequency shifts, may be to ensure that every note (or at least one ormore notes, in some embodiments) in the musical scale resonates with thehuman body. In such embodiments a step in the Rezonyx process may be torecalibrate every note in the musical scale to a frequency that isresonant with the human physiology.

For example, nearly all music today is tuned using a modern standard of12-tone temperament scaling and A 440 base reference. Such tuning isperceived by our ear as sound and music but may not provide optimalresonance with aspects of our human physiology. Such suboptimalresonance characteristics may be analogous to a radio signal with a lotof static. By recalibrating the frequencies of sound using systems andmethods described herein, notes within the music and other audiomaterial may resonate better with the human physiology, e.g., analogousto improving clarity of a radio signal.

The ability to put forward a new process of tuning for all instrumentsmay provide musicians and artists with a new way to create music thatprovides a more engaging experience.

III. Example: Parallel Input Sources (FIG. 7-9)

In some embodiments, a Rezonyx processing system may be used forpolyphonic retuning or other processing of parallel input sources. Suchinput sources may include, for example, one or more simultaneous audioinputs, video inputs, and/or data inputs, or any combination thereof.For example, referring to FIG. 7 a system 700 for polyphonic retuning ofmultiple parallel input sources may be incorporated within a guitarhaving multiple strings, e.g., strings 710-1, 710-2, 710-3, 710-4,710-5, and 710-6. Each such string may be fed into a separate process,e.g., Rezonyx Processors 750-1, 750-2, 750-3, 750-4, 750-5, and 750-6,respectively, each of which may be used for polyphonic conversion offrequencies in the respective string, e.g., using processes and methodsas described and shown herein. A mux 760 or other module may be used todownmix or multiplex the parallel processed signals and send to anamplifier 770 for output to a speaker 780 or other output device. Insome embodiments, system 750 may be incorporated on a chip or othersubstrate or module within a musical instrument, or may be incorporatedin a “black box” device that includes Rezonyx processors 750-1, 750-2,750-3, etc. for real-time processing and polyphonic retuning of multipleinputs from one or more instruments.

In some embodiments, such parallel polyphonic retuning of a guitar maybe incorporated within a guitar, amplifier, computer, or black-boxdevice during live band performances, where performing music materialtends to get emotional physical responses.

Turning now to FIGS. 8A, 8B, and 8C, in some embodiments, parallel audioand/or data inputs or outputs may be employed (as used herein “data” mayinclude audio signals, video signals, instructions, or other informationor signals), for example where a parallel data input is eithertransformed, utilized or passed through the audio processing to the downmix stage within a Rezonyx system. For example, referring to FIG. 8A, asystem 800 may incorporate one or more parallel data inputs 810 andaudio inputs 820, each of which may be passed into and/or through aRezonyx processor 850. In some embodiments, the data may includeinstructions or information to be used by the processor 850 inpolyphonic retuning or other processing of the audio signal to produce arecalibrated, retuned or otherwise enhanced audio output 860. Forexample, input data 810 may be data or instructions from a responsestate selector or other module that may be used to instruct theprocessor 850 to retune the audio input 820 to a desired frequency orcombination of frequencies to produce a desired effect, e.g., inaccordance with the frequency characteristics and responses described inSection V below.

In another example system 802 as shown in FIG. 8B, parallel data input810 and audio input 820 may be processed by the processor 850 to producetwo or more outputs 862, 864, which may include, for example audioand/or data outputs. One example could be a hearing aid device wherebythe device sends an instruction input 810 to the Rezonyx system 850 andwhere the instruction is changed on output 862 indicating status ofcompleteness. The output change could be signaled via a specificfrequency that is beyond human range, e.g. 30,000 Hz, a specificwaveform fingerprint or via a data output. In another example,

In each of the examples shown in FIGS. 8A and 8B, a data input 810 couldbe included alongside the audio input signal 820, e.g., for the purposesof providing an instruction on how to process the signal. Data could beinput from external source, stored in database, stored within theprocessor 850, and/or provided using a selector switch, audio cues,dial, tuner, filter, or other device or method.

In other example embodiments 804, as shown in FIG. 8C, one or moreparallel outputs 862, 864, may be produced by a Rezonyx processor 850from a single audio input 810. For example, in some embodiments, output862 may be an enhanced audio or audio downmix, and output 864 may be aseparated data output, e.g., where the data is derived from theprocessing of the audio signal and/or produced by the Rezonyx processor850 or another source. In another example, the audio input 810 may beprocessed and downmixed in 850 and sent through different outputs 862,864 depending upon range of frequencies per output.

An example of using a data input or other fixed or tunable instructionfor Rezonyx processing is a hearing aid device. For example, in someembodiments, a hearing aid device may send an instruction to the Rezonyxprocessor, e.g., where the instruction is changed on output indicatingstatus of completeness. Such output change could be signaled via aspecific frequency that is beyond human range e.g. 30,000 Hz, a specificwaveform fingerprint, or via a data output.

For example, referring to FIG. 9, a hearing aid system 900 having aRezonyx processor 950, which may be embedded, for example, in a chipsetwithin a hearing aid or otherwise in communication with the hearing aid.In this example, processor may receive audio inputs 910 (e.g., auditorysounds to be processed for better hearing by the user) and one or moreparallel data inputs 920, which may comprise an instruction that isgenerated live or from a preset definition such as a definition ofhearing impairment, e.g. hearing loss in this patient is between 800 and1000 Hz. In this example, Rezonyx 950 could utilize this instruction 920then harmonically split 952 the input material 910, e.g., between 800and 900 Hz (low) and 901 Hz and 1000 Hz (high). Then, the processor mayshift 954 the low material to 699 Hz to 799 Hz and high material to 1001to 1101 Hz. Once shifted, the processed material would be downmixed 956against the other material to provide an audio output 960, where thewhole range of information is perceived, e.g., in someone who cannotperceive audio due to hearing loss.

Such uses for the hearing impaired may address known issues withspecific frequency loss due to industrial deafness, and the technologycould keep people working on job sites where a full range of audioinformation is necessary.

In another example, a data input could instruct Rezonyx to processmaterial and on complete a switching signal is sent to output via aspecific frequency that is beyond human range, e.g., 30,000 Hz, aspecific waveform fingerprint or via a data output. An example of thiscould be once the processing has started sending a switching signal tochange mood lighting.

In some embodiments, systems may be configured to employ serial inputsinstead of or in addition to parallel inputs to achieve some of theaspects, features or advantages described in examples above.

IV. Example: Real-Time Processing Devices (FIG. 10)

The hearing aid embodiment described above is one example of a deviceincorporating a Rezonyx system and methods for real-time processing ofaudio signals. At least two other examples are described in thissection.

Referring to FIG. 10, another example of a live or real-time processingdevice is a headphones device 1000 incorporating a Rezonyx system 1010and processor 1050 for polyphonic retuning of music or other audiosignals played through the headphones. In this example, system 1010 maybe incorporated on a chipset or other substrate within the headphones1000, e.g., within the housing of an earpiece 1004. They system 1010 mayinclude an input interface 1020 for receiving music or other audiosignal. Such interface may be wired or wireless (e.g., Bluetooth, Wi-Fi,or other wireless communication protocol), or simply may receive thesignal passed from a standard input interface already incorporatedwithin the headphones. The signal from the input 1020 may be passed tothe Rezonyx processor, e.g., for polyphonic retuning, filtering,splitting, shifting, downmixing, and/or other processing as describedelsewhere herein. In some embodiments, a data input, such as from aresponse state selector 1030 or other switch, dial, database, or otherinput source, may be used to provide instructions to the processor 1050,e.g., for retuning of the signal to produce a desired response, result,or effect. The processed signal is then passed to an output 1060, whichmay include an amplifier, stereo speakers, or other output device todeliver music or other audio to the user.

In some embodiments, system 1010 may be incorporated within a musicplayer, such as an iPod, mobile phone, or other mobile device or mediaplayer, where the processed signal is then transmitted to standard wiredor wireless headphones, earbuds, speakers, or other audio devices.

Similarly, a real-time audio processing system 1010 may be incorporatedwithin any “black box” device, e.g., where the box includes an interface1020 for plugging in an audio input and a response state selector 1030for selecting different response states, such as excited, calm, healing,or other desired responses, e.g., to produce output frequencies thathelp trigger certain emotional responses in listeners from relaxedstates to excited and energized states, and all states in-between.

Example use cases may include troops in battle, where troops are in abattle ready state and cannot switch off. Information shows cases ofpost-traumatic stress disorder (PTSD) may be caused from not being ableto deep sleep and induce rapid eye movement (REM). Systems describedherein may be used to provide acoustically enhanced audio material tohelp calm troops and get them into REM sleep, which could aid in theabatement of PTSD symptoms and provide refreshed troops who are morefocused and ready for the demands of their job.

Similarly, sports athletes or anyone looking for performance enhancementmay utilize Rezonyx technology inside of headphones as a pre match prepup whereby focus and drive need to be elevated through the use of audiomaterial. Similarly, applications for a black box embodiment could beanywhere from gymnasiums for promoting excitement during and afterworkouts to hospitals for pre operation relaxation, through to crowdcontrol, riots or holding cells, or places where hostile environmentsneed a sense of calm.

V. Frequency Band Principles

Master Frequency of 1122 Hz

UT—396 Hz—Intent: Turning Grief into Joy, Liberating Guilt & Fear

This frequency liberates the energy and has beneficial effects onfeelings of guilt. It cleanses the feeling of guilt, which oftenrepresents one of the basic obstacles to realization, enablingachievement of goals in the most direct way. The ‘Ut’ tone releases youfrom the feeling of guilt and fear by bringing down the defensemechanisms. 396 Hz frequency searches out hidden blockages, subconsciousnegative beliefs, and ideas that have led to your present situations.

RE—417 Hz—Intent: Undoing Situations and Facilitating Change

The next main tone from the Solfeggio scale produces energy to bringabout change. This frequency cleanses traumatic experiences and clearsdestructive influences of past events. When speaking of cellularprocesses, tone ‘Re’ encourages the cell and its functions in an optimalway. 417 Hz frequency puts you in touch with an inexhaustible source ofenergy that allows you to change your life.

MI—528 Hz—Intent: Transformation and Miracles (DNA Repair)

Tone ‘Mi’ is used to return human DNA to its original, perfect state.This frequency brings transformation and miracles into your life. Theprocess of DNA reparation is followed by beneficial effects—increasedamount of life energy, clarity of mind, awareness, awakened or activatedcreativity, ecstatic states like deep inner peace, dance andcelebration. Tone ‘Mi’ activates your imagination, intention andintuition to operate for your highest and best purpose.

FA—639 Hz—Intent: Re-Connecting and Balancing, Relationships

Another frequency from the sacred Solfeggio scale. It enables creationof harmonious community and harmonious interpersonal relationships. Tone‘Fa’ can be used for dealing with relationships problems—those infamily, between partners, friends or social problems. When talking aboutcellular processes, 639 Hz frequency can be used to encourage the cellto communicate with its environment. This ancient Solfeggio frequencyenhances communication, understanding, tolerance and love.

SOL—741—Hz Intent: Solving Problems, Expressions/Solutions

It cleans the cell (“Solve polluti”) from the toxins. Frequent use of741 Hz leads to a healthier, simpler life, and also to changes in diettowards foods that are not poisoned by various kinds of toxins. Tone‘Sol’ cleans the cell from different kinds of electromagneticradiations. Another application of this sound frequency is solvingproblems of any nature. The fifth frequency of the Solfeggio scale willalso lead you into the power of self-expression, which results in a pureand stable life.

LA—852 Hz—Intent: Awakening Intuition, Returning to Spiritual Order

Tone ‘La’ is linked to your ability to see through the illusions of yourlife, such as hidden agendas of people, places and things. Thisfrequency can be used as means for opening a person up for communicationwith the all-embracing Spirit. It raises awareness and lets you returnto spiritual order. Regarding cellular processes, 852 Hz enables thecell to transform itself into a system of higher level.

Additional research conducted by Dr. Leonard Horowitz claims to haverevealed three more Solfeggio frequencies:

SI—963—Hz Awakening

This tone awakens any system to its original, perfect state. It isconnected with the Light and all-embracing Spirit, and enables directexperience, the return to Oneness. This frequency reconnects you withthe Spirit, or the non-vibrational energies of the spiritual world. Itwill enable you to experience Oneness—our true nature.

174 Hz

The lowest of the tones appears to be a natural anesthetic. It tends toreduce pain physically and energetically. The 174 Hz frequency givesyour organs a sense of security, safety and love, encouraging them to dotheir best.

285 Hz

This frequency helps return tissue into its original form. The 285 Hzfrequency influences energy fields, sending them a message torestructure damaged organs. It also leaves your body rejuvenated andenergized.

The tones are: 396, 417, 528, 639, 741 & 852. Following the patternestablished by these original tones, additional frequencies can becalculated. There are three frequencies which can be calculated belowthe 396 before breaking the pattern (63, 174, 285) and there areinfinite frequencies that can be calculated above the 852. See below:

VI. Brain Wave Principles

3rd Stage Brain Wave Entrainment

There are four recognized brain wave ranges: Beta (14-30 Hz) is presentin normal waking consciousness; Alpha (7-14 Hz) in states of relaxation;Theta (4-7 Hz) in meditative states; and the slowest, Delta (0.5-4 Hz)in deep sleep and profound meditative states. The most recentlyresearched brain frequency is Gamma, which is the fastest, about 30.0 Hzand higher. Stage 3 finalizes the processing of psychoacoustic cues byincorporating Binarual beats into the source material.

Binaural beats, or binaural tones, are auditory processing artifacts, orapparent sounds, caused by specific physical stimuli. This effect wasdiscovered in 1839 by Heinrich Wilhelm Dove and earned greater publicawareness in the late 20th century based on claims coming from thealternative medicine community that binaural beats could help inducerelaxation, meditation, creativity and other desirable mental states.The effect on the brainwaves depends on the difference in frequencies ofeach tone: for example, if 300 Hz was played in one ear and 310 in theother, then the binaural beat would have a frequency of 10 Hz.

Five Categories of Brainwaves

Category 1: Beta Brainwaves

(14 to 32 Hz alert, focused)

Beta is the most common brain wave pattern: Beta brainwaves are producedwhen we are wide awake, alert, active and engaged in mental activity,usually involving more the rational, reality-oriented left hemisphere ofour brain. When beta wave activity becomes very intense, our brainhemispheres become less synchronized. Beta state is required to functionproperly in your everyday life.

Features and Benefits of a Beta State

This is the brainwave for the fight-flight response

Increased concentration and alertness

Improved logic, reasoning and critical thinking

Feelings of anxiety, stress, scattered unfocused thought

NOTE: Excessive Beta brainwaves are also a feature of insomnia

Category 2: Alpha Brainwaves

(7 to 14 Hz relaxed yet aware, meditative)

These are lower frequency waves: The state is generated when ourthoughts are really not concentrated and our minds wonder freely, or weare in a relaxed state such as meditating or daydreaming. We alsoexperience Alpha Brainwaves when we are gently busy with routine taskslike pottering in the garden, taking a shower, putting on makeup, doinglight housework. Alpha is considered to be the bridge between theconscious mind and the subconscious mind.

Features and Benefits of an Alpha State

-   -   Our brain hemispheres become naturally synchronized, or in-phase        with each other.    -   Relaxed detached (absent-minded) awareness and daydreaming mind.    -   Enables us to remember our dreams and meditative states.    -   Link between conscious and subconscious mind, gateway to        meditation.    -   Receptive to casual and auto—suggestions (hypnosis state)    -   Increased vividness benefits creative visualization and triggers        imagination    -   Increased memory retention, concentration & focus for super        learning

Health benefits include:

-   -   Reduced anxiety    -   Alleviates stress and depression    -   Reduces chronic pain    -   Reduction of high blood pressure    -   Increases athletic performance    -   Increased cerebral blood flow    -   Increased motivation, energy, and happiness

Category 3: Theta Brainwaves (3.5 to 7 Hz Deep Relaxation, TwilightState)

Theta brainwave states have been used in meditation for centuries: It iscommon for people to feel as if they are in a trance, where the mindfeels as though it may have gone to sleep although it is conscious ofwhat is happening around it. Theta induces a capacity for prolongeddaydreaming, where a loss of time may be experienced.

Theta waves are also conducive to visualization and creativity and themind in this very relaxed state is highly receptive to direct suggestionunder hypnosis. As with Alpha, in Theta our brain hemispheres aresynchronized and we experience whole brain functioning.

Features and benefits of Theta brainwaves

Increased sense of inner peace and emotional stability

Deep relaxation

Improved memory

Heightened intuition and inspiration

Calms the chatter of your mind

Increased psychic abilities and sense of spiritual connection

Health benefits of Theta brainwaves

Speed healing, improved physical healing

Sleep onset and better more restful sleep

Release beneficial hormones related to health and longevity

Reduce mental fatigue

Reduction of anxiety and stress

NOTE: Research has proven thirty minutes a day of Theta meditation candramatically improve a person's overall health and well-being. Thetameditation has also been known to result in a reduced need for sleep.

Category 4: Delta Brainwaves

(0.1 to 3.5 Hz deep sleep)

This is the slowest band of waves that our brains produce and they occurwhen we are in deep, dreamless sleep. These waves are very beneficialfor the body, which restores and heals itself when in this state. Thedelta state releases anti-aging hormones, including melatonin and DHEA.Human growth hormone (HGH) is another anti-aging hormone that isincreased when delta brainwaves are occurring inside the brain, due tothe stimulation of the pituitary gland. HGH maintains the skin, bonedensity, cartilage, and the joints in your body as well as speeds up thehealing process of joint and cartilage injuries. HGH can also help healphysical pain.

In healthy amounts, delta brainwaves can also cause a person to have anadvanced state of empathy, understanding, and compassion for others.

Delta is the place of deepest relaxation, deepest healing, deepestspiritual connection and deepest connection with the subconscious mind.It is considered to be the gateway to the unconscious mind and thecollective unconscious, bringing access to the universal psyche or mind.

Category 5: Gamma Brainwaves

(40 Hz or higher: Zen mind mastery)

Gamma brainwave states are the most rapid in frequency. Gamma has longbeen considered the brainwave that is able to link and processinformation from all parts of the brain. It is the frequency that bringswith it the ability to process large amounts of information inrelatively small amounts of time. Think of generating more Gammaactivity as getting a processor upgrade for your brain.

Unfortunately Gamma brainwaves have received the least attention andresearch, although more attention is currently being paid to them.

Having high amounts of Gamma Brainwave activity has been associatedwith:

Having high levels of intelligence

Being compassionate

Having high amounts of self-control

Having greater than average feelings of natural happiness.

Increased awareness through your five senses

Research has indicated at moments when bursts of precognition orhigh-level information processing occur, your brainwaves briefly reachthe Gamma state.

Each of us can use brainwave entrainment to achieve a variety ofresults. You may want to target a specific brainwave frequency range tohelp you relax. On the other hand you may want to increase you creativeenergy, improve your memory, deepen your sleep or get better resultswhen playing a sport.
